GRP Trench Jack
Frequently Bought Together
Trench jacks are placed in-between the GRP Shoring rails. The trench jacks, also known as hydraulic cylinder or Hydraulic struts must be connected to the shoring system before it is placed into the trench. Once the GRP shoring system is placed into the trench these Hydraulic struts are pumped until the GRP panels push firmly against the trench excavation walls, continue to pressurise until the bucket pump registers between 450 - 750psi & there is no sign of pressure loss.
In order to pressurise these jacks we offer a 10L bucket pumps & hose.
